Brad King 09b2f1c3f5 Windows: Find Program Files directories more robustly from environment
In Modules/Platform/WindowsPaths.cmake our previously recorded
environment variable combinations no longer seem to be correct.  For
example, a 64-bit cmake binary may see ProgramW6432 in the environment
and end up not considering the "ProgramFiles(x86)" variable.  Instead
check for all possible environment variables in the preferred order and
then remove duplicates.
